Showerheads, like toilets are regulated by EPAct92, which established a flow rate limit of __ gallons per minute:
  1. 2.0
  2. 2.5
  3. 3.0
  4. 3.5
Explanation
Answer: B - Showerheads have a flow rate limit of 2.5 gpm at 80 psi of water pressure. Replacing an older showerhead, which may flow at 5 gpm or more, with a unit that uses 2.0 gpm or less can pay for itself through reduced water and energy expenses in just a few months.
